74LVC16245A; 74LVCH16245A

16-bit bus transceiver with direction pin; 5 V tolerant; 3-state

[1]

The circuit performs better when RL = 1 kΩ,

Test data is given in Table 9.

Deﬁnitions for test circuit:

RL = Load resistance.

CL = Load capacitance including jig and probe capacitance.

RT = Termination resistance should be equal to output impedance Zo of the pulse generator.

VEXT = External voltage for measuring switching times.
